Troubleshooting
Problem
No lights are lit
on the Wireless
PC Card
The Lnk LED
is off
I am associated
and connected
to an Access
Point, but I
cannot see the
other computers
on the Ethernet
side of the
network.
Cause
The MA521 Wireless PC
Card is not inserted
properly into the CardBus
slot on your PC. Or the
proper MA521 Wireless PC
Card driver is not loaded.
The MA521 Wireless PC
Card is not associated to
any Access Point properly.
You may not have
configured the wireless
parameters of the wireless
nodes to be the same as the
Access Point.
This could be a physical
layer problem or a network
configuration problem.
Solution
• Remove and reinsert the MA521 Wireless
PC Card.
• Check the device manager in Windows to see
if the adapter card is properly recognized in
the Windows operating system. Reload the
driver if necessary.
• Try to install the MA521 Wireless PC Card
in different CardBus slot if it's available.
• The Access Point may not be powered on.
• The Access Point and the MA521 Wireless
PC Card are not configured with the same
wireless parameters. Check the SSID, and
WEP encryption settings.
• The Access Point may be out of range. Try
moving the system closer to the Access Point
or readjusting the antenna on the Access
Point. You may also move the Access Point to
a higher location for better signal reception by
the MA521 Wireless PC Card.
• Check to make sure that the Access Point
is physically connected to the Ethernet
network.
• Make sure that the IP addresses and the
Windows networking parameters are all
configured correctly.
